Is CEBPE p.Arg265His (c.794G>A) pathogenic?

CEBPE p.Arg265His (c.794G>A) is classified Uncertain significance in CEBPE (ClinVar, Single submitter, 1 submitter; last evaluated 2022-08-19). AlphaMissense: likely benign (0.3223); Very rare (popmax 0.004%, afr); Associated with specific granule deficiency.

What condition is associated with CEBPE p.Arg265His (c.794G>A)?

CEBPE p.Arg265His (c.794G>A) is associated with specific granule deficiency (ClinVar).

How common is CEBPE p.Arg265His (c.794G>A) in the general population?

CEBPE p.Arg265His (c.794G>A) is very rare (popmax 0.004%, afr) (gnomAD).

What do computational predictors say about CEBPE p.Arg265His (c.794G>A)?

AlphaMissense predicts likely benign (score 0.3223) — an in-silico prediction, not a clinical call.

CEBPE p.Arg265His

Q: How is Recurrent infections due to specific granule deficiency inherited?

Typically Autosomal recessive (Orphanet). A genetic counselor can assess individual risk for a family.

ClinVar classifies this uncertain; the computational predictors unanimously lean tolerated — a triage signal, not a reclassification

AlphaMissense carries the ACMG weight for missense; REVEL and SaProt are independent agreement signals.

Rarity supports pathogenicity (ACMG PM2); frequency above a disease-specific BA1/BS1 threshold argues against it. A variant frequent in one ancestry group can be near-absent in others, so a single global figure can mislead.
